The diisocyanate used is preferably an aromatic compound and can be mono-blocked with a phenol, t-butyl alcohol or, preferably, caprolactam. The elastomeric particles and blocked diisocyanate are reacted in a solvent, after which the reaction product is recovered as a dry foam which is then powdered for moulding use. The powdered material, optionally together with another hydroxy-functional material, e.g. ethylene glycol or the unreacted elastomeric particles, can be moulded and crosslinked ; useful applications include cover sleeves for flexible cables and conduits, flooring materials and flexible housings.
